Sigma Aldrich Fine Chemicals Biosciences Hirudin from leeches lyoph
Hirudin is a 7 kDa acidic protein containing 65 amino acid residues that has an isoelectric point of 3.5-4.0. It is not glycosylated and lacks tryptophan arginine and methionine residues. It is chemically stable between pH 2-12 and at temperatures up to 80C.
Cayman Chemical Harmalol hydrochloride hydra
A β-carboline alkaloid and an active metabolite of harmaline; an inhibitor of DYRK1A (IC50 = 0.63 µM); an inhibitor of MAO-A (IC50 = 0.66 µM); selective for DYRK1A over Cdk1, Cdk5, CK1α1, Clk4, DYRK2, Pim-1, and GSK3β but also inhibits DYRK1B and Clk1 at 10 µM; inhibits proliferation of H4 human glioblastoma cells (IC50s = 23.7 µM); reduces TCDD-induced increases in CYP1A1 levels in HepG2 cells and prevents TCDD-induced activation of AhR in guinea pig hepatic cytosolic extracts; reduces glutamate-induced cytotoxicity, cytochrome c release, caspase-3 activation, and ROS production in PC12 cells at 25 µM
Cayman Chemical DoxapramhydroCLOrID hydra 25mg
A central respiratory stimulant; increases respiration and phrenic nerve activity in anesthetized cats at a dose of 1.0 mg/kg; acts through carotid chemoreceptors, lacking activity in anesthetized cats following carotid denervation
Cayman Chemical PemetrexedodIum salt hydra 5mg
An antifolate with anticancer activity; an inhibitor of thymidylate synthase and dihydrofolate reductase (Kis = 109 and 7 nM, respectively); has increased potency for thymidylate kinase when polyglutaminated (Ki = 1.3 nM); an inhibitor of glycinamide ribonucleotide formyltransferase (Kis = 9,300 and 65 nM for the non-glutaminated and polyglutaminated enzyme) and aminoimidazole carboxamide ribonucleotide formyltransferase (Kis = 3,600 and 265 nM for the non-glutaminated and polyglutaminated, respectively); inhibits proliferation of CCRF-CEM cells but not 5,10-dideazatetrahydrofolate-resistant CR15 cells (IC50s = 0.254 and 200 µM, respectively); reduces tumor growth in A549, H1299, and PC-9 NSCLC mouse xenograft models but not in models using the same cell lines overexpressing thymidylate kinase
